LOOM.

Specification of Letters Patent No. 13,022, dated June 5, 1855.

To all 'whom t may concern: Y

Be it known that we, JOHN SHINN and WILLIAM WHITESIDE, of theconsolidated city of Philadelphia, twenty-firstvward, late the boroughof Manyunk, State of Pennsylvania, have invented some new anduseful'Improvements on Power-Looms; and we do hereby declare that thefollowing is a clear and exact description of the construction andoperation of the same, reference being had to the annexed drawings,makinga part of this specication, in which-l Figure 1 is a front view;vFig. 2 is a birdseye view; Fig. 3 is an end view; Fig. 4 is a sectionshowing the horizontal levers C, C, the vertical'levers J, J, the wiresW, W, the hooks A, A, the traveling rods E, E, and guides D, D; Figs. 5and 6 are enlarged views of the swinging plate K, K; Fig. 7 is anenlarged view of the vibrating staple or a loop m, att-ached to the rodR, R; Fig. S is an enlarged view of the levers L, L; Fig. 9 is anenlarged view of the balanced catch N.

We will now proceed to describe their construction and operation, byreferring to the annexed drawings; similar letters of reference indicatecorresponding parts.XV

The loom framing can be made in any known style or design in which thereis a shaft X,on which is an eccentric grooved cam S, in which groovethere is a roller on a stud attached to one end of the lever T, whichworks `on a,1 stud in the center of the lever T, fastened to the loomframing. From the ends ofthe lever T are connections V, V, whichcommunicate the motion to the levers C, C, to open the warp-shed evenlyboth ways. At the lifting and depressing ends of the levers C, C, areattached straps 2 2, which pass over the rollers F, F, and connect withthe traveling rods E, E, in the loops O, O, and as the shed closes therods E, E, will bring the hooks a, a, to their proper position to beready for the next movement of the pattern roller. The pattern rollercommunicates motion to vertical the backward motion of the lay; and asthe lay goes back the plates K K will come in contact with the cams onthe levers L L, and depress them at that end, and cause the other end torise, which is connected to the picking staifspulleys by means ofstraps, and gives motion to the pickers in the usual manner. Alsoproviding the rod G' in front of the reed, and made to vibrate onarms,which are attached to studs or pins fastened on the back of the layin such a manner that the rod will rise and fall freely'in front of thereed. The rod Gr is connected to the rod I, which is an ordinaryprotecting rod with the protecting finger H on it by means of theconnections y y. On the rod I is a finger e e, under which is a cam 0 cattached to the loom frame; as the lay goes back the linger e e on therod Gr comes in contact with the cam o c, causing the rods I and Gr torise for the shuttle to pass under the rod G, and should the shuttlefail to enter the box, it will arrest the downward motion of the rod Gr,and cause the linger H, on the rod I to strike the lever P on the breastA, which will shift the driving strap, and immediately arrest thefurther advance of the lay, and prevent any injury to the warp threads.Also providing the loom with the staple or loop M (Fig. 7 attached tothe rod r r, and placed on the front of the lay near the mouth of theshuttle box, and operated by the swell N; as the shuttle enters the boxit presses out the swell N, and the staple falls across the race of thelay, and if there be no weft thread across the opening in the race ofthe lay the staple M will fall through the opening, and strike thebalanced catch U (Fig. 9), which is placed a little below the race, soas to let the shuttle pass over it. If the thread is broken or thebobbin is exhausted the staple M will press the catch under the arm onthe rod at the connection T, and cause the finger H to strike the leverP, and stop the loom as before described. W'e do not claim thecontrolling of the whole series of harness or a part of them, by onelever at the top of-the loom and a 1iumber of levers at the. bottom ofthe loom;

What we do claim as our improvement,

and desire the same secured to us accordingly, is-

1. The combination and arrangement of one lever at the bottom of theloom, with one at the top, in such a manner as to control any number oflevers of harness that may be desirable, and open the warp-shed evenlyboth ways, as described.

2. We also claim the combination of the guides, traveling rods, therollers F, F, and straps connecting the lever C, C, for the purpose ofbringing the hooks to their proper place in time to be ready for theneXt movement of the pattern roller, as described.

3. We do not claim the vertical levers for the purpose of opening thewarp shed-but we do claim them in combination with the wires IV, W, forthe purpose of actuating the hooks, as described.

4. We do not claim the swinging plates K, K, but we do claim thecombination of the swinging plates K, K, with Vthe levers, L, L, or theequivalent arrangement of the same for the purpose of actuating thepickers as described.

5. We claim the rod, Gr, or its equivalent, so arranged with the rod, I,that when the shuttle is arrested in front of the reed, it will causethe protecting finger H, to strike the lever P, and shift the drivingstrap and immediately arrest the further advance of the lay, asdescribed.

6. The following we claim as an improvement on the machine of E. Burt,dated June 20th, 1845, in which the said E. Burt claims the hanging weftprotector on the race of the lay itself: The hanging of the loop on therace we do not claim, but that which we claim as our improvement anddesire the same secured to us accordingly, the balance catch U, incombination with the loop M, and operated by the swell N, so that whenthe weft thread is broken or exhausted it will immediately arrest themotion of the loom in the first forward motion of the lay as described.
